ASr and CSR are deffent.
ASR=Answerd calls/ Seizured calls
If you have ofer flowin your trunks you shold add that aslo along with sezures.
CSR=Call success/Call attempts
normally in anetwork CSR will be 97%.But ASR will be between 30to 50% only. In my netwok i observed CSR of 98% and ASR 35%
Hi Sujeesh,
Thanks for your clarification.
What I understood your reply is Call Success Ratio is nothing but ABR. Pleas correct me, if i am wrong. Thanks.
1 st case.. calls get connection .
In wirless senario , If BTS receved SERVICE CONNECT COMPLTE MESSAGE message from MS and it(BTS) should send ack for this meassage to MS
hi Sujeesh & Balakrishnana
Thanks for the Discussion threads,
I think the idea is a bit clear now abt CSR related to BTS & MS in a wireless network.
But what about CSR & ASR in CCS7 network ?
Because though the CSR at BTS end is 97% call failure is lot especially Call drops especially on 31st of Dec. that is I believe MSC resources were not available that is SM’s in this cases for CCS7 what should be the definations?
